The Heisenberg Uncertainty Principle Demonstrated with An Electron Diffraction Experiment
Matteucci, Giorgio; Ferrari, Loris; Migliori, Andrea
European Journal of Physics, v31 n5 p1287-1293 Sep 2010
An experiment analogous to the classical diffraction of light from a circular aperture has been realized with electrons. The results are used to introduce undergraduate students to the wave behaviour of electrons. The diffraction fringes produced by the circular aperture are compared to those predicted by quantum mechanics and are exploited to present and discuss the Heisenberg uncertainty principle. (Contains 4 footnotes and 3 figures.)
